Now, I guess a lot of farmers will spit on you and your meds if you grow in Miracle Grow, and I want to know why.
First, lets examine pictures of my budding OG, which is producing some very good buds that will be highly medicating, this was grown in Miracle Grow potting mix and with a very stable pH of 7.9 or 8
With a pH of 8, there has been no deficiencies, and overall no real issues using Miracle Grow, and a pH of above 7 ( which I've read isn't recommended for soil growing ).
All in all, Miracle grow has been a miracle for me on my first grow ever!
Thanks for looking!
